Thanks for the pics.
there is only one component I can't make out but I'm sure it's a 12V regulator and that's the one near TP9. the black rectangular part. Otherwise this is a basic BOB with some code running on the PIC/AVR (i'll bet on a AVR for aurdinio) but could be wrong. code would mainly be handling the Limit switch -> freq conversion and the ATC maybe.
if that's the case you dont' need to reproduce the whole board. just the Limit switch and ATC code.
If you want I can email you some nice hi res pic's. When I try to upload them here they have issues. I can email then to you if you like. I've sent one set to a guy already.
The Fadal is a TRM mill.
It has color LCD monitor and from what I understand the latest version of there control before the were no longer made.
It has a 8gig memory expansion card as well.
The deal with a pro type control is everything you touch for it is high as h*ll. Just to add a fourth axes is stupid money. I don't want to be shackled to a couple of part vendors that are licking there chops every time I need to upgrade or fix the control.
My plan is to get PathPilot up and going test it on my Tormach to ensure it works properly and get it setup running Clear Path motors. I'm going to fix the Fadal contol and part it out to offset the cost of this build.
The ridge tap mean nothing to me. I tap with a floating taping and I do just fine.
